Application filed February 17,1904. Serial No. 194,027.

To LM wiz/0m it may con/cern:

Fig. 2 a second narrow tube 7L made ot glass Be it known that I, IGNACYMosoIoKI, a for instance and closed at one end is imcitizen of Austria,residing at Fribourg, in l the Republic of Switzerland, have inventedcertain new and useful Improvements in Electric Condensers; and I dohereby declare the following to be a full, clear, and eX- actdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a condenser the coating of which consists inthe usual manner of electrolytic conductors. The novelty of thiscondenser is thatone of its electrolytic coatings is contained in theinterior of a tubular dielectric which is itself sunk in the othercoating. Y

In the accompanying drawing Figures 1 and 2 are sectional elevationsshowing two forms of the invention.

In the form illustrated in Fig. l a is a vessel made of insulatingmaterial, which contains a iluid electrolytic conductor such as sulfuricacid, potash lye, soda lye, etc. Into this, the electrolytic conductorwhich forms one coating of the condenser, a narrow tube closed at oneend and made, for example, of glass, is dipped, the top of the tube bpassingfthrough a junction c of the vessel a, and the interior thereoflikewise containing a fluid electrolytic conductor as an inner coating.This tube which acts as a dielectric is wound in spiral form so thatwhile of considerable length it occupies exceedingly little space. Aconducting wire d made, for example, of lead runs through the wholeinterior length of the tube and projects from the top thereof. On thebottom of the vessel a is an, electrode plate e made, for example, oflead and connected with a conducting wire g (lead wirefor instance) thatruns through a junction f of the vessel a. The two conducting wires dand g serve for connecting the two coatings with an external circuit.`Owing to the conducting wire d running through the whole length of thetube b the resistance in this tube is greatly diminished.

In the form of the invention illustrated in mersed in the electrolyticconductor contained in the vessel a, the top of this tube runningthrough the junction f and likewise containing a Huid electrolyticconductor which acts as a coating. This tube 7L which acts as adielectric is like the tube b wound as a coil and conccntrically to thattube. Through the whole interior of the tube /L a conducting wire g runswhich projects from the top thereof and Aserves for connecting theelectrolytic coating contained in the tube L with an external circuit aswell as Jfor reducing the resistance in this tube. AThe electrolyticcoating contained in the vessel a is the external coating common to bothof the tubes b and 7L, so that this form of the invention represents twocondensers arranged in series.

Thetubular dielectric containing the one coating has the advantage overplate-shaped dielectrics in the absence of corners where the electricitybecomes condensed; besides this, tubes are less easily broken. rlhecoatings can be easily insulated from each other, as only the placewhere the tubular dielectric passes through the vessel (L needs to beinsulated.

What I claim as my inventionand desire to secure by Letters Patent is:

An electric condenser comprising a vessel of insulating materialcontaining an electrolyte, two coiled tubular dielectrics, the coils ofone surrounding the coils of the other, both being immersed in theelectrolyte contained in the vessel, each tubular dielectric containingan electrolyte conductor, and conducting terminals inserted within thetubular dielectrics and immersed in the electrolytic conductorscontained ther'ein.

In testimony whereof I have aflxed my signature to this speciiication,in the presence of two witnesses.
